In describing the invention, I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views.

The curler illustrated in Figures 1 through '7 has a mandrel I formed ofmetal. This mandrel may be of any length and diameter desired and forthe major portion of its length is circular in cross section and of thesame diameter. Its upper end is reduced to form a finger hold 3 which isalso circular in cross section and its lower end is reduced to form aneck 6 which is rectangular in cross section and formed with a threadedsocket 5 to receive a screw 5 as shown in Figure 6.

The hair engaging lock which is associated with the spindle is alsoformed of metal and consists of a disc 7 which turns relative to themandrel and upper and lower discs 8 and 9 firmly carried by the neck 1and formed with rectangular openings Ill and H to receive the neck.

Referring to Figure 6, it will be seen that when the discs 8 and 8 areapplied to the neck and the screw 6 screwed into the socket 5 with itshead bearing against the under face of the disc 9, the two discs will beprevented from moving off of the neck and since the disc 8 is formedwith a hub l2 against which the disc 9 bears, the two discs will beretained in spaced relation to each other and the disc l which isdisposed between the discs 8 and 9 and formed with an enlarged openingl3 to receive the hub of the disc 8 will be permitted to turn freelybetween the discs 8 and 9 relative to these discs when the disc 1 isgrasped by its flange l4 andmotion imparted to rotate this disk relativeto the mandrel and discs 8 and 9. A flange I5 is formed about margins ofthe disc 8 to bear against the flange M as shown in Figure 6 andreferring to this figure, it will be seen that the flange l4 not onlyextends upwardly above the disc I but also projects downwardly toencircle the disc 9. Therefore, the disc I will be prevented fromtilting transversely upon the hub l2 and will be permitted to rotatefreely relative to the discs 8 and 9. The opening l3 formed in the discI is extended to form a throat I 6 opening through the marginal flange94 of this disc and this throat is intended to register with slots H andi8 formed in the discs 8 and 9. It will be noted that the slots ll and58 are so cut that their inner ends are extended at one side as shown atl9 and 25, thereby causing these discs to be formed with fingers 2| and22 which are intended to extend across a lock of hair and force the hairinto the inner end portion of the side extension N5 of the slot l5. Thisside extension is gradually reduced in width towards its inner end andtherefore the hair will be firmly wedged into this portion of the slotit when the curler is in use. Referring to Figures 4 and '7, it will beseen that from the outer end portion of the finger 22 projects a lug 23which bears against the lower portion of the flange I4 as the disc I isturned and by contacting with a tooth or abutment 24 struck inwardlyfrom the flange M, will serve to limit rotation of the disc in eitherdirection. Therefore, proper registration of the slots l6, l! and I8will be assured and also rotation of the discs relative to each other ina closing direction will be limited.

When this device is in use, the disc I is grasped by holding its flange[4 between a thumb and one or two fingers of one hand and by graspingthe knob 3 of the mandrel between fingers of the other hand, the mandreland disc 1? may be rotated relative to each other in a direction whichwill dispose the slots of the three discs in alignment as shown inFigure 2. A look of hair can then be drawn forwardly through the alignedslots and turning motion then imparted to the mandrel to rotate thediscs 8 and 9 and cause the slots to be closed and the lock of hairfirmly held. This lock of hair is then coiled about the mandrel by useof a winder or in any other desired manner after which it will becovered with a wrapper dipped in chemical and thrust into a heatingelement of a permanent waving ma" chine. It will, of course, beunderstood that the hair can be first engaged through the aligned slotsand coiled about the mandrel after the slots have been closed or thehair coiled about the mandrel and then engaged through the slots and thediscs I turned to close the slots. This is optional with the operator.

The form of curler illustrated in Figures 8 through 15 is in manyrespects similar to that previously described and has a mandrel 25formed with a turning head 26 at its outer end and a reduced rectangularneck 2'! at its inner end. The lock carried by the inner end portion ofthe mandrel is of a different construction from that shown in Figures 1through '1 and consists of a housing 28 having upper and lower walls 29and the lower wall carrying a marginal wallor flange 5i which is reducedin thickness to form a seat 32 against whichthe wall 29 bears andextended inwardly as shown in Figure 14 to overlap the disc or wall 28and retain it in engagement with the marginal wall of the housing.Between the walls 29 and 38 of the housing is located a disc 33 formedwith a rectangular opening S to receive the neck of the rod or mandreland this disc is firmly fixed upon the neck to prevent movement of therod outwardly through the opening 35 formed in the disc or wall 29.Therefore, by holding the housing and imparting rotary motion to themandrel, the disc 33 may be rotated within the housing and the finger3G3 moved across from the position shown in Figure 12 tothat disclosedin Figure 13.- When the disc 33 is cut to form the finger 35:, there isalso provided a slot 39 adapted to register with the slots 3'! and .38in order that hair may be engaged through the lock prior to movement ofthe disc to the position shcvm in Figure 13 and in order to limitrotation of the disc within the housing, there has been provided a pinto which projects inwardly to engage abutments 4! and :12 correspondingto the abutments 23. Since the slot 39 has a portion extending about thedisc and reduced in width towards its inner end and the slots 31 and 38have side extensions 31 and 38, hair wil be wedged in these portions ofthe slots and firmly gripped.

' The operation of this form of curler need not be described as it issimilar to that of the device illustrated in Figures 1 through '7.

The curler illustrated in Figures 15 through 21 also has a mandrel orrod 33 carrying a lock o at one end, but the lock is quite different inits construction from those previously described. In this embodiment ofthe invention, the lock consists of a housing 45 having an upper wall iswhich fits within the marginal wall rising from the bottom of. thehousing. A flange 68 projects upwardly from margins of the upper wall 46and about this flange is formed a bead 49 which rests against the wall'll. The inner end portion. of. the mandrel. 43 extends through anopening so formed centrally oi the wall 46 into the housing and the endof the mandrel termihates in a squared neck El which engages through arectangular opening 52 formed in the hub 53 of a latch By referring toFigures 20- and 22, it will be seen that the latch is formed with alongitudinally curved bill 55 extending circum ferentlally of thehousing in radial spaced relationto the rod.

An opening 55 is formed centrally of the wall 45 of the housing andthrough this opening ispassed a screw which is screwed into a socket 58formed axially of the rod and has'its head overlying portions of the hu53 about the neck 5! to firmly hold the latch upon the neck and preventthe rod from slipping out of the lock.

A look of hair is to be passed through the housing similar to the mannerin which hair is drawn through the lock previously described and inorder to do so, the bottom 45 of the housing and its upper wall or coverGd have been formed with aligned slots 53 and 59. At one side of theseslots, the marginal wall 4? is cut away to receive the hinge car 69 of akeeper 6% through which extends a screwor pivot pin 62 carried by hingeoars t3 and 64 formed upon the bottom and upper walls, and, therefore,the keeper will be pivotally mounted for swinging movement into and outof a closed position as shown in Figures 7 and 18. The marginal wall ofthe housing is also cut away at the opposite side of the slot to permitthe bill 65 of the keeper to swing 'inwardl,y and between its hinge ear59 and bill 65, the keeper is formed with side flanges 56 between whichongage the bill of the latch when the latch is moved into lockingengagement with the keeper.

When this form of curl-er is in use, the lock of hair is passed throughthe slots of the housing and its cover or upper wall and coiled. aboutthe mandrel as previously described. In order to se cure the hair inposition through the lock, the keeper is swun inwardly towards a closedposition after the hair has been engaged through the slots 58 and e Thehousing and mandrel can 'hen be turned relative to each other in adirection to move the bill of the latch across the aligned openings andas this movement takes place, the bill 55 will overlap the bill 650i thekeeper and exert a cam action which will force the keeper inwardly untilthe hair is very firmly gripped between the keeper and inner ends of theslots of the housing.

Since the free end portion of the bill 55 engages between the sideflanges 65' of the keeper, transverse movement of the latch and keeperrelative to each other will be prevented andthe keeper will be forcedinwardly towards a closed position without danger of side strain whichmight bend or break the pivot pin. When the rod and housing are turnedin anopposite di rection relative to each other, the keeper will bereleased and may be swung outwardly to an open'orinoperative position,thereby releasing the hair and permitting it tobe drawn outwardly end isenlarged asjshown at Si to form ahead bored to provide a socket 68communicating with a passage 69 extending axially through the rodfromthe socket to the upper end of therod. The lower end portion of thesocket is addi tionally enlargedin diametenl thereby forming a seat torotatably receive a. neck H projecting upwardly freonv the center of the.top or upper wall E2 or the housing #3 forming the body por tion of alock M corresponding to the lock 44. The cover or upper wa11'12 restsupon the marginal wall of the housing where it is held in place by ascrew 15 engaged through hinge ears 7'! and T8 and serving as a pivotpin for a keeper 19 corresponding to the keeper 5i. A flaring flangeormarginal wall all projects upwardly about margins of the cover orupper wall 12 with its ends terminating at opposite sides of a slot 8!formed in this cover and from one of the side arms or wings 82 of thekeeper 79 extends a lip 83 forming a continuation of the wall 80 whenthe keeper is swung inwardly to the closed position shown in Figures 25and 27.

.By referring to Figure 27, it will be seen that when the keeper is in aclosed position, it moves into the slot 3! of the cover 72 and also intoa corresponding slot 84 formed in the bottom of the housing 13. A key orrod 85 carrying a latch 86 at its lower end which is firmly fixed to thesame extends through the hollow stem or mandrel and by' rotating thestem the bill 8? of the latch may be moved into and out of position tooverlie the keeper and secure the same in a closed position with a lockof hair gripped between the keeper and inner end of the slot formedinthe upper wall or cover and bottom of the housing. The rod or stem 85is of such length that it'projccts beyond the upper end of the rod orstem and upon this protrudinglupper' end of the rod which is squared asindicated by dotted lines in Figure23, is applied a finger engagingelement 38 which is removable in order that the rod may be slidlongitudinally through the mandrel when it is necessary to remove themandrel. Wings 89 which'are preferably four in number project radiallyfrom theupper end portion of the rod to permit this rod to be readilyrotated when the lock 14 is held between a thumb and finger of one handandthe wings gripped between a thumb and finger of the other hand, andin order to control rotation of the rod, there has been provided acoiled spring 535 firmly seated in the collar ll which serves as abearing for the lower end-of the rod and this spring extends into'thesocket 68 with its free endin contact withwalls of the socket. .133 thisarrangcn'lent, the rod or stem may be readily rotated in one directionabout the stern and collar H but if it is attempted to turn the rod inan opposite direction the sharp free end of the spring will bite intowalls of the socket and prevent rotation in this direction. Therefore,the rod can only be turned in one direction and a lock of hair engagedthrough the lock it will be coiled in a proper direction about the rod.A tongue 9! formed of thin sheet metal extends longitudinally of the rodand this tongue which .is curved transversely in order to fit closelyabout the rod as shown in Figures 24 and 25 is pivotally mounted at oneend to the rod a short dis-- ,tance from the inner ends of the wings 89as shown at 92. Therefore, when a lock of hair is to be coiled abouttherod, its free end'portion may be first engaged between the rod and thetongue 9i andfirmly gripped by the tongue during a coilingoperation.Therefore, the hair will be firmly held andprevented from slippingduring or after it has been coiled.

When this form of curler is in use, a lock of hair is passed through theslots 84 and 8!, of

the cover 12 and housing 13 after the keeper I9 has been swung towardsthe closed position shown in Figure 5, the head or finger engagingelement 88 of the stem will be grasped and rotary motion imparted to thestem to swing the bill 8! of the latch toward the keeperand cause thebill to move to overlapping engagement withthe keeper and force thekeeper tightly into place within the housing of the lock. The free endportion of the lock of hair is then engaged between the rod and thetongue 9! and by grasping the wing the rod can be easily rotated in acounterclockwise direction and cause the lock of hair to be coiledtightly about the rod. Either a croquignole coil or any other typedesired may be formed by properly guiding the lock of hair during acurling operation.

The curler illustrated in Figures 29 through 35, has a mandrel 9! formedof metal or any other suitable material and at the lower end of thismandrel is provided a lock {72 for connecting the mandrel with a lock ofhair to be curled. The lock has upper and lower plates 93 and 94, theplate 83 being formed with a depending hub terminating in a squared neck$6 received in a square opening 9i formed centrally of the plates ordiscs 9 This hub 85 retains the plates spaced from each other and sincethe plate or disc 54 is carried by a squared neck, the two plates willturn as a unit. A screw 98 serves to hold the lower plate in place aboutthe neck and by being screwed into a threaded socket 953 formed in astem Ebb, serves to connect the stem with the upper plate. This stemfits into a seat or socket l9! formed centrally of the upper plate anabout this socket is formed an annular groove Hi2, serving as a seat forthe inner end of the mandrel and when this mandrel is seated in theannular groove, frictional engagement will take place and cause the twoplates to turn with the mandrel. By exerting pull upon the mandrel, itmay be readily separated from the lock and drawn away from the same torelease a coil of hair after a curling operation has been completed.

Referring to Figures 33 and 34, it will be seen that the stem IE6 isreceived in a pocket I03 formed longitudinally of the mandrel from itsinner end and this stern slides through a bushing use which fits tightlywithin the pocket of the mandrel and serves to guide sliding movement ofthe mandrel toward and away from the lock. The bushing also serves toengage a head Hi5 carried by the stem and prevents sliding movement ofthe mandrel away from the look beyond the position shown in 34. By thisarrangement, a lock of hair may be coiled tightly about the mandrel withthe mandrel in the position shown in Figure 33 and after a curlingoperation is finished, the mandrel may be drawn through the coil of hairto the position shown in Figure 3e, thereby releasing frictional grip ofthe hair and permitting it to expand suiliciently to break its grip andallow the mandrel to be slid out of the curl.

,If so desired, the mandrel may be directly secured to the upper plateas previously shown and described instead of being mounted for movementtowards and away from the lug.

The plates 93 and 94 cooperate to form a housing between which a keeperIE6 is pivotally mounted for movement from an opened position shown inFigure 32 towards a closed position shown in Figure 30, in which thekeeper extends 'ciroumferentially of the housing across hair receivingrecesses 10'! and I68 cut radially of the plates or discs and havingside extension [09 and H0 into which the hair is to be forced and firmlygripped when the device is in use. When a lock of hair is engagedthrough the opposed hair receiving recesses of the plates or walls ofthe housing, the keeper is to be moved inwardly and forced into tightgripping engagement with the hair. In order to do so, there has beenprovided a band or collar i I l which fits snugly about the housing incontacting engagement with marginal edges of the upper and lower wallsand referring to Figures 33 and 34, it will be seen that this collar orband is formed with an inwardly projecting, circumferentially extendinglip H2 which projects into the space between these walls and preventsmovement'of the collar out of its proper engagement with the housing. Anupstanding marginal flange I !3 carried by the upper wall or plate alsobears against the collar and assists in retaining the collar in properengagement with the two walls and guiding rotation of the collar. inspaced relation to each other a distance slightly greater than the widthof the hair receiving recess of the housing in order that easy accessmay be had to the hair receiving recess when fitting a lock of hair intothe same.

Referring to Figures 30, 31 and 32, it will be that as one end of theband, the lip H2 and face of the hand are cut straight across iagonallyto form an undercut cam surface I M, whereas at the other end of thecollar the lip is gradually reduced in width to form a cam surface l 85.By this arrangement, a lock of hair may be engaged through the recessesof the plates 33 and 84 and by holding the band or collar with the thumband fingers of one hand and turning the mandrel with the other hand inthe direction indicated by the lower arrow in Figure 31, the keeper ortongue Hi6 will be guided inwardly by the cam surface H5 and movedinwardly across the hair receiving recesses to a position in which thelock of hair will be forced into the end portions H39 and H0 of therecesses and firmly gripped.

When the mandrel is rotated in the opposite direction indicated by theupper arrow in Figure 31, the free end of the keeper which is bevelledas shown at H6 will make contact with the bevelled end face H4 and beguided outwardly towards the opened position as shown in Figure 31 andfinallymoved to the fully opened position shown in Figure 32. By thisarrangement, the tongue or keeper moves automatically into and out of aposition across the hair receiving recesses and the device can be veryeasily engaged with or disconnected from a lock of hair;

Insofar as the croquignole winding device, as illustrated particularlyin Figures 23 to 28, inclusive, is concerned, the important feature ofthe device is the linking together'of a lock directly on the shaft, rodor mandrel upon which the croquignole winding of the hair isaccomplished. Whereas, heretofore it has been necessary to utilize aseparate locking element into which the hair curling rod is inserted inorder to lock the hair on the rod and the rod in position with respectthereto, I have provided a device in which there is a combination lockand hair curling lock for croquignole winding. Such a combination devicesaves time, labor and expense in operation and will eliminate thepossibility of burning the scalp, which quite frequently occurs throughthe use of the well known separable locking elements used on haircurling mandrels or rods.

Ends of the collar or band terminate From the foregoing description ofthe con.- struction of my improved device, the method of applying thesame to use will be readily under= stood. It will be seen that I haveprovided a simple, inexpensive and eficient means for carrying out theobjects of the invention and while I have particularly described theelements est adapted to perform the functions set forth, it is ob usthat various changes in form, proportion and in the minor details ofconstruction may be resorted to, without departing from the spirit orsacrificing any of the principles of the invention.
